Posh is one of the newer Revlon shades I've seen at local drugstores. It's a beautiful green creme that applies like butter. Only two coats are needed to make this beauty opaque. There really isn't much more to say about Posh: it's green and it's awesome.
I used two coats for my pics over the Seche Vite base coat. I used two coats of Seche base coat, because Posh is really pigmented, and it would stain my nails if I didn't. No top coat.
